Answer:
[tex]7y=-5x-11[/tex]
Step-by-step explanation:
Since it says the lines are parallel both of their gradients will be same.
so gradient of line 1 = [tex]y=\frac{14-5x}{7}[/tex] = [tex]y=\frac{14}{7}-\frac{5x}{7}[/tex]= [tex]-\frac{5}{7}[/tex]
so equation of line 2 = [tex]y-y_{1}=m(x-x_{1} )[/tex]
= [tex]y-(-3)_{}=\frac{-5}{7} (x-(-2)_{} )[/tex]
= [tex]y +3=-\frac{5}{7}x+\frac{10}{7}[/tex]
= [tex]y =-\frac{5x+10}{7}-3[/tex]
= [tex]7y=-5x-11[/tex]
Step-by-step explanation:
basically a line equation typically looks like
y = ax + b
with a being the slope, and b bent the y-intercept (y value when x = 0).
5x + 7y = 14
7y = -5x + 14
y = -5/7 x + 14/7 = -5/7 x + 2
so, wie know the slope of the original line : -5/7 .
any line parallel to it must have the same slope.
our desired line looks like
y = -5/7 x + b
to get b we use the provided point (-2, -3).
-3 = -5/7 × -2 + b = 10/7 + b
-21/7 = 10/7 + b
-31/7 = b
and the full equation is
y = -5/7 x - 31/7
7y = -5x - 31
5x + 7y = -31

Answer:
the difference between the highest and lowest values in a set of numbers.
Step-by-step explanation:
At a community fund raiser event, bracelets cost $3 and necklaces cost $6. Complete the patterns in
the first two columns for the cost of 0, 1, 2, 3, and 4 pieces of jewelry. Write the ordered pair for the
corresponding terms in the third column. Then graph the ordered pairs
Answer: Attached photos, and the last question of my explanation.
Step-by-step explanation: If "bracelets cost $3 and necklaces cost $6" that means we will multiply.
1. for Bracelets (1 bracelet = $3)
(0 x 3 = 0) 1. $0
(1 x 3 = 3) 2. $3
(2 x 3= 6) 3. $6
(3 x 3 = 9) 4. $9
(3 x 4 = 12) 5. $12
Explanation: We have to multiply 5 different numbers to fill in the 5 rows of bracelets & necklaces. (0,1,2,3,4 = 5 numbers). For example, if we buy 2 bracelets, 1 bracelet = $3 and 3*2=6 so it would be 6.
2. for Necklaces (1 necklace equals $6)
(0 x 6 = 0) 1. $0
(1 x 6 = 6) 2. $6
(6 x 2 = 12) 3. $12
(6 x 3 = 18) 4. $18
(6 x 4 = 24) 5. $24
3. coordinates
1. (0,0)
2. (3,6)
3. (6,12)
4. (9,18)
5. (12,24)
Putting the coordinate pairs on the graphs: the first number is x and the second is y.
4. I displayed a photo of what the chart, and graph should look like.5. What is the relationship between the corresponding terms in the two sequences: The second sequence is the product of multiplying sequence 1 and sequence 2.
the greatest common factor of 3x^4-12x^2
Answer:
3x^2
Step-by-step explanation:
3x^4-12x^2
Factoring out 3x^2
3x^2 ( x^2 -4)
We can factor (x^2-4) since it is the difference of squares
3x^2 ( x-2) (x+2)
The greatest common factor is 3x^2
Let's find the G.C.F. (Greatest Common Factor) of 3x⁴-12x².
The key words here are "common" and "greatest".
Here are some common factors:-
3
3x
3x²
x
x²
And the greatest common factor is:-
3x²
[If Necessary]
Factor it out by dividing the terms in the polynomial by the GCF:-
x²
4
Subtract the terms:-
(x²-4)
And put the G.C.F. outside the parentheses:
3x²(x²-4)

A linear function is represented below.
Which function has a greater y-intercept than the function in the table?
A. y = 4x
B. y = –2x
C. y = –x – 1
D. y = –0.5x + 5
here is the chart it wouldn't let me do a screenshot:
X, Y
-2,-6
0 0
3 9
Solution:
D. y = –0.5x + 5
In this chart, the slope, (m):
[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\hookrightarrow \sf \frac{-6-0}{-2-0}[/tex]
[tex]\hookrightarrow \sf \frac{-6}{-2}[/tex]
[tex]\hookrightarrow \sf 3[/tex]
Equation:
[tex]\sf y_1-y= m(x_1-x)[/tex]
[tex]\hookrightarrow \sf y-(-6)= 3(x-(-2))[/tex]
[tex]\hookrightarrow \sf y+6= 3x+6[/tex]
[tex]\hookrightarrow \sf y+6-6= 3x+6-6[/tex]
[tex]\hookrightarrow \sf y= 3x[/tex]
⇒ Thus we found in the chart, the slope is 3 and y-intercept : 0
A = y-intercept : 0B = y-intercept : 0C = y-intercept : -1D = y-intercept : 5From this D only has the greatest y-intercept than the chart.

In the figure below, m || n and t is a transversal line. If ∠7 = x +14 and ∠1 = 2x -8, what is ∠4?
∠4 and ∠1 are opposite angles, and since opposite angles are equal, ∠4 = 2x - 8
(if u need a specific number)
∠1 is corresponding to ∠5, and since corresponding angles are equal, ∠5 = 2x-8
∠7 is supplementary to ∠5, and since supplementary angles add up to 180, x + 14 + 2x - 8 = 180
-> 3x + 6 = 180
x = (180-6)/3 = 58.
Since ∠4 = 2x - 8 -> ∠4 = 2 x 58 - 8 = 108.

Describe how to compare the two ratios 5:8 to 7:9. Tell each step to set up the ratios, then explain what to do to be able to compare the ratios. Finally make sure to answer how the ratios compare. ~ 100 POINTS AND ILL GIVE YOU BRAINLIEST IF YOU ANSWER CORRECTLY AND 5 SENTENCES NEEDED
Answer:
5/8 is smaller.
Step-by-step explanation:
A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777
Then to compare them you see which is smaller or bigger.
0.77777 is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.
Steps:-
First rewriteThen convert to fractionsThen divide both[tex]\\ \rm\rightarrowtail 5:8::7;9[/tex]

The least value of the function at which the pendulum is in the center is 0 and the position of the pendulum when t = 4.25 sec. is 4.24
The graph of the functionThe function is given as:
y = 6cos(πt)
See attachment for the graph of the function
The least positive value of tThe value of t is given as: -0.5
From the attached graph, the smallest value of the function when t = -0.5 is 0.
Hence, the least value of the function at which the pendulum is in the center is 0.
The position of the pendulum when t = 4.25 sec.We have:
y = 6cos(πt)
Substitute 4.25 for t
y = 6cos(4.25π)
Evaluate
y = 4.24
Hence, the position of the pendulum when t = 4.25 sec. is 4.24

A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the discount price?
The discount price of the lawn mower purchased by the store is $193.45.
What is the discount price?The first step is to determine the selling price of the lawn mower.
Selling price = ( 1 + 1.60) x $82.67 = 214.94
Now determine the price after the discount has been applied.
Discount price = (1 - 0.1) x 214.94 = $193.45

What is Inverse Function?Inverse Function is a function that swaps domain and range.
What are domain and range?Domain is the set of all x-values while Range is the set of all y-values, can be defined in coordinate point as (x,y).
StepsIf (x,y) is an original function then (y,x) will be an inverse function of original.
We are given the function g = {(a,1),(b,2),(2,3),(d,4)} - swap the domain and range.
Therefore, the inverse of function g is [tex]\displaystyle \large{g^{-1}}[/tex] = {(1,a),(2,b),(3,2),(4,d)}

Which of the following number CANNOT represent the probability of an event?
A. 0.888
B. 0
C. 4.2
D. 0.39
Answer:
c
4.2 would mean a 420% chance of something happening which doesnt make sense
The number 4.2 cannot represent the probability of an event because it is greater than one.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of an event must be less than or equal to one.
So 0.888 can represent the probability of an event because it is a non-negative number that is less than or equal to one.
0, cannot represent the probability of an event because it is a non-negative number but it is not less than or equal to one. This number represents an impossible event.
4.2, cannot represent the probability of an event because is greater than one which means it represents an event that is certain to occur, which is not a probability.
0.39, can represent the probability of an event because it is a non-negative number that is less than or equal to one.
Therefore, the number 4.2 cannot represent the probability of an event because it is greater than one.

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
Determining the equation:
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
Simplifying both sides:
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
Using cross multiplication:
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
Dividing 82 both sides:
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes
